 | Liu, Feng | Simple generic method for predicting the effect of strain on surface diffusion | We show, by first-principles calculations, that the effect of external strain on surface diffusion is inherently correlated with the intrinsic surface stress induced by the adatom along its diffusion pathways. We demonstrate a simple generic method for a priori predicting quantitatively how an ext... | Surface diffusion; First-principles calculations; Adatoms | 2001-11 |

 | Liu, Feng | Quantum size effect on adatom surface diffusion | Using scanning tunneling microscopy, we demonstrate that the nucleation density of Fe islands on the surface of nanoscale Pb films oscillates with the film thickness, providing a direct manifestation of the quantum size effect on surface diffusion. The Fe adatom diffusion barriers were derived to be... | Quantum size effect; QSE; Adatoms; Surface diffusion; Fe islands; Nanoscale metallic structures; Epitaxial growth; Pb films | 2006-12 |
